Yesterday I got back from Costa Almeria where I spended 4 days visiting hotels, again for work.
Unfortunatly, I'm very disappointed about the Costa itself. I'm not a big fan of Spain and certainly not of Roquetas de Mar... But that's personal opinion.
I can understand people who want to go there, as there is a kilometers long boulevard to make nice walks, Aguadulce is a nice bay also and you're not far from Almeria city, wich has a nice Alhambra to visit.
For families there is a theme park called Oasis Mini Hollywood. It's a cowboy theme park with a zoo attached to it, wich makes a great daytrip for families !
Some highlight hotels :
Zimbali Playa - Vera
Playacapricho - Roquetas de mar
Cabo Gata garden - El toyo
Mediterraneo Park - Roquetas de mar
